#webxml ⇒ Object

Extra configuration for web.xml. Controls how the dynamically-generated web.xml file is generated.

  • webxml.jndi – the name of one or more JNDI data sources name to be available to the application. Places appropriate <resource-ref> entries in the file.

  • webxml.ignored – array of key names that will be not used to generate a context param. Defaults to [‘jndi’, ‘booter’]

Any other key/value pair placed in the open structure will be dumped as a context parameter in the web.xml file. Some of the recognized values are:

  • webxml.rails.env – the Rails environment to use for the running application, usually either development or production (the default).

  • webxml.gem.path – the path to your bundled gem directory

  • webxml.jruby.min.runtimes – minimum number of pooled runtimes to keep around during idle time

  • webxml.jruby.max.runtimes – maximum number of pooled Rails application runtimes

Note that if you attempt to access webxml configuration keys in a conditional, you might not obtain the result you want. For example:

<%= webxml.maybe.present.key || 'default' %>

doesn’t yield the right result. Instead, you need to generate the context parameters:

<%= webxml.context_params['maybe.present.key'] || 'default' %>
